Halloa Easter bunny's 🙂

a couple of months ago now, I came across some new battery packs from ZOHD.. Now ZOHD is known for foam FPV airaplanes, but definately not for battery packs..
Sooo these packs are basically specifically made for the type of airplanes they sell.. And I would say making prefab LION packs is a good idea since not everybody wants to weld / solder 18650 packs together...

But.. on seeing the packs at BG I felt like taking the 4S pack "a bit" outside of it's comfort level....

The 4S pack: ZOHD 4S Lion pack

The 2S pack: ZOHD 2S Lion pack

Sooooo let us then see if the pack survived 🙂

LiPo will go down to 2.8V as well - but repeated and it will eventually damage the cells. I would suggest that ZOHD quote 2.8V as the absolute lowest similar to LiPo ... because actually as you know a LiPo is only a LiIon with Polymer addition. So in fact should have same voltages.

Noted that the absence of the Polymer reduces charge and discharge rates.

I would think your low battery warnings are because the AMP rate is too high for the ZOHD pack and causing it to voltage drop so far that you get alarm warning.

The warning-levels are simply Bataflight settings, but yes.. if you strain the pack more the voltage will drop well and good..

More of an off the wall question.  What is your impression of the longer clover leaf antenna?

I like the idea of raising the antennas above a noise field away from fans and video amps. Another plus is lifting it above your head away from body capacitance thereby even less directional through body shielding.

Then the downside.  Are you now creating more losses given the distance between the sma connector and the cover leaf. The higher the frequency the more critical the loss factor.

I have this in my checkout basket amongst other stuff waiting for me to pull the trigger.
Fly like your mad at it.

I personally haven't moved to this longer antenna to combat noise but I know from experience our heads are a great way to block some signal 😃 
My range / coverage is better with this longer antenna and there might be a bit of loss due to the length, but any advantage of a shorter antenna will be outdone by your head being in the way of things 🙂

Works for me and thank you. You've just helped with my suspicions and worry with an unbiased opinion on this antenna. 

I think I will stay with my lipo's while running a quadcopter but wow.. I can foresee some big returns on the atypical park flyer.  Fly all afternoon and quit only because you're gettting bored with it. 

An interesting and worthwhile test Mr. Dutch.  You brought forward some valid information using this platform. 👍
Fly like your mad at it.

I knew lion packs had worse performance under load than Lipos but even only drawing 10 amps during some parts of your video there was some pretty serious sag. Interesting watch though

true.. it takes a specific type of quad to have this pay off 🙂 
The amp-O-meter in that quad is kinda not-so-good by the way 😋  but still.. these are only 10C batteries, so it makes sense they don't really like providing lots of Amps 🙂
